Blue toruses = 15 protons
Red toruses = 7 nuclear electrons
Atomic number of O15 = protons (15) - nuclear electrons (7) = (8), with structure Li6 He3 Li6
Oxygen 15 transformed by positron emission from a source of a photon by decomposition, while
electron component of the photon captured (at the center) of
Oxygen 15
transition form,
generating Nitrogen 15
nucleus (stable).
